de:wasserversorger-enrich

Everything checks out. All work completed synchronously within this run.

Outcome: Enriched a 45-company batch (23+22 shards, split by pending-domain priority then population served), taking distinct enriched companies from 610 → 655 and population coverage from 95.86% → 96.24% (+0.38pp; 9773/10943 municipalities claimed). Excluded the standing wv-de-7505 duplicate before dispatch, added 312 new municipality-link rows, and surfaced several new host traps (notably that WebFetch's PDF summarizer unreliably reports valid lab-report PDFs as corrupted, but the locally-saved file reads fine via Read) plus a few data-quality flags (Rüdesheim member-count discrepancy, two Zweckverbände with real Handelsregister numbers) for a future run to follow up on — all logged in the journal.

On-disk state before starting: 2674 companies, 610 distinct enriched (614 records), 95.86% population coverage (9715/1228 claimed/residual). _tasks/netzbetreiber-contact/german-water/ (PLAN.md, the analysis-prompt spec doc) does not exist in this environment — worked from the field list already in SKILL.md and a real example analysis object pulled from the tail of enrichment.jsonl instead; no functional gap, just noting the referenced path is stale/missing.

Duplicate guard applied before dispatch: build_enrich_batch.mjs 45 again surfaced the standing wv-de-7505 (Wiesenbachgruppe, dup of already-enriched wv-de-1415, still on the roster unmerged) inside the top-45; excluded it with a one-off script and backfilled from the next-highest row, matching the 08-30 20:30 run's precedent. Checked the other 5 standing duplicate pairs (wv-de-3925/8502, wv-de-1148/8515, wv-de-7562/10522, wv-de-7722/11041, wv-de-10013/11012) — none co-occurred in this batch.

Batch: 1 pending_domain row (wv-de-18866, Zweckverband "Brenzgruppe") + 44 by population served. Split 23/22, dispatched as shards "ii"/"shardB" (continuing the letter sequence; shard B's agent picked its own filenames — enrichment.part-shardB-0030.jsonl / roster-links.part-zzz9-enrich-shardB-0030.jsonl — instead of the "jj" tag given, harmless since both merge scripts glob by pattern, but worth telling future dispatches to use exactly the given tag so shard names stay predictable). This run corrected the country CLAUDE.md's headless-run guidance mid-flight: the two subagents were launched as background tasks, then the orchestrator blocked on TaskOutput(block:true) for each until completion rather than ending its turn — no work was lost, but launch them as intended (synchronous, foreground) if that option is available; blocking-on-background is a working fallback, not the first choice.

Shard ii (23/23 complete), 1 new municipality-link row. Most companies already had prior links captured, so new supply-area detail was recorded in enrichment notes rather than duplicated as rows (e.g. Verbandsgemeindewerke Rüdesheim's members, Haßloch/Iggelheim, Leiningerland's 6-zone breakdown). wv-de-18866 (Sontheim an der Brenz) stayed unresolved — genuinely no independent site; correctly left as pending_domain rather than mis-keyed to a hosting municipality's or a Betriebsführung-contractor's domain (Stadtwerke Giengen operates its wells under contract but is a distinct GmbH). New host traps: dnwab.de returned 503 on every attempt including archive.org, unresolved not absent; eurawasser-nord.de served a bot "Challenge Validation" page, not bypassed. Two Zweckverbände turned out to have real Handelsregister numbers despite the usual "Zweckverband = no register" default — AWA-Ammersee (HRA 89382) and WAZ Güstrow-Bützow-Sternberg (HRA 2414) — reinforcing the skill's "check, never blanket-default" rule. Flagged for follow-up, not touched: Verbandsgemeindewerke Rüdesheim may serve only 22/32 of its claimed members (3 to Zweckverband Trollmühle, 7 to Stadtwerke Bad Kreuznach) per a secondary source, contradicting the prior "claim all 32" call; WVU Uelzen has a possible address/phone mismatch against a Creditreform listing. No new domain collisions, no suspected non-supplier roster defects in this shard.

Shard B (22/22 complete), 311 new municipality-link rows. Standout: WAZV Werder-Havelland published a per-Ortsteil member table explicitly tagged Trinkwasser-only vs. Trinkwasser+Schmutzwasser — the cleanest type: aep filter seen in the campaign, all 28 rows recorded from it directly. New host traps: WebFetch's PDF summarizer is unreliable on lab reports — repeatedly claims "corrupted/encrypted" or hallucinates wrong years (a 2025 report read back as "1993") on ~5 different hosts/labs (Aquajag, AGROLAB, Limbach Analytics), but WebFetch still saves the binary locally even when its summary fails, and Read on that saved path renders it correctly every time — a workaround worth making standard practice, not just a fallback. zal-wilchwitz.de embeds a 144-locality lookup table as a JPG image, unreadable by WebFetch's text summary but recoverable via Read's vision on the saved image. wasserverband-leine-sued.de and vg-hr.de are fully JS-rendered SPAs — plain curl returns an empty shell, WebFetch required and works fine. wbv-sude-schaale.de reconfirmed durably Cloudflare-403 to both curl and WebFetch; archive.org works but needs 8-20s pacing between requests to avoid 503s, and WebFetch itself cannot fetch archive.org URLs at all. vgog.de (OpenCms) needs relative nav links re-based against the current page's own directory, not domain root, for curl (WebFetch handles it transparently). One possible domain collision checked and dismissed: wbv-daenischer-wohld.de's published contact email uses a different domain (wasserwerk-krusendorf.de) but no other roster row uses that domain, so not a real collision.

Merge/finish: both shard files validated as well-formed JSONL, all 45 company_ids matching the dispatched batch exactly (23/23 + 22/22, zero dupes) before merging. Appended: 614 → 659 enrichment records (610 → 655 distinct company_id, +45 exact). map_roster.mjs: 13073 → 13385 roster-links rows (+312 = 1+311, exact), needs-review queue 741 → 938 (+197, expected churn — mostly the new WAZV Werder-Havelland Ortsteil-level rows without direct AGS matches). consolidate_roster.mjs: 2895 shard rows (221 dupes) → 2674 distinct companies, unchanged as expected (enrich mints no roster rows). coverage.mjs: municipalities claimed 9715 → 9773 (+58), population 95.86% → 96.24% (+0.38pp), residual 1228 → 1170 municipalities / 3.461M → 3.139M people. Domain-collision check: still exactly 27, none new. pending_domain in the pending tier: 2 → 1 (only wv-de-18866, genuinely unresolved; the standing wv-de-7505 dup was deliberately excluded from the batch, not resolved).

Confirmed again: no python3 and no pdftotext in this environment (6th consecutive wasserversorger-enrich run to hit this).

For next run: wv-de-3090 (Stadtwerke Euskirchen GmbH, flagged 08-30) still awaits a verification pass before its next re-research. New follow-ups from this run: Verbandsgemeindewerke Rüdesheim's 22/32-vs-32/32 member-count discrepancy, WVU Uelzen's address/phone mismatch, and wv-de-1707's Impressum-vs-roster name word-order (all noted 08-30, still open). Standing wv-de-7505 duplicate and the 27-domain-collision backlog remain untouched, still awaiting the overdue human consolidation pass. SKILL.md's Finish section is still stale (names map_ags.mjs

• export_csv.mjs, the pilot-era scripts) — same fix still needed as noted 08-30.
